An electron beam display, in which light extracting efficiency from phosphor and a bright-portion contrast are improved is provided, has: an electron-emitting device, a metal back, and a phosphor dot which is disposed in opposition to the electron-emitting device through the metal back and emits light responsive to an irradiation with an electron beam emitted from the electron-emitting device; and further has a face plate having a black member which is disposed in opposition to the electron source through the phosphor dot and has an aperture in a region in which the phosphor dot is formed. A region irradiated with the electron beam emitted from the electron-emitting device is not larger than the phosphor dot, a part of the black member is disposed in the region irradiated with the electron beam, and at least a part of the aperture is disposed outside of the region irradiated with the electron beam.
